In fluid technology isolation valves are used. These control the opening and closing of the ducts. Thereby the discharge, flow through and the admission of gases and fluids through the piping system is regulated.

There are different designs. One of these is the globe valve. This is lifted vertically before the opening whereby it operates as an opening and closing mechanism.

The second type is the annular valve. This has an opening such as a circular ring. Isolation valves include controllabe as well as variable valves.

In contrast to ball cocks for example isolation valves, which have only two state functions - to open or close, isolation valves can adjust the flow rate continuously on demand.
